Thank you so very much Gentleman....M-Tecs & Larry Gibson for chiming in with your experience in .22lr BR. As you can see, this thread has been a 'huge learning curve' for several of us Neophytes...your information & data is so much appreciated!
I have been mulling on different ways to approach this 'Reading the Wind & Doping' ... up until now we haven't considered the wind at all and have been concerned with the technicalities of a sound rifle and matching the rifle with the best ammunition we could afford...next it was proper form & bench accessories to send the rounds as best as possible...but...now the wind has to be considered and mastered as well.
First thing I did was to build new wind flags from the heaviest engineers tape I have...made them 26" long with a reinforced swivel tab on top and approximately 24" of free ribbon to show the wind strength and direction. I put a spike in the bottom of an old broom handle and a screw in the top to hold the ribbon...
The spike in the bottom of the broom handle is to stab in the dirt...the broom handle has the ribbons elevated up maybe 12" over the height of my barrel on the bench...
Today I don't have any method of judging wind velocity and don't have any proper targets to gather data on...but...they are on order & will arrive soon...
Today, I had one box of 40 rounds left of the Eley 'tenex' & have been using that in the Savage MKII. (a 'peep & globe sighted rifle I have temporarily installed a scope on to find a benchmark of accuracy for that rifle, then I'll go back to the peep & globe) I thought I'd experiment with that rifle even though this thread is about my CZ452, I shoot Eley Match in the CZ and am flat out until tomorrow, got 3 bricks coming to my FFL.
Anyway...here's the follies for today...(I should mention that this MKII is currently sighted for the POI to hit a 1/4" high of the cross hairs of the target spot right on center line...that was set that way so I wouldn't obliterate the center of the spot and make it hard to align the scope, I intend to readjust the scope so that the POA will be the POI now that we are dealing with the wind)
I wanted to see if this right hand twist would duplicate any of the 'predicted POI's in the charts previously posted.
I had the bright idea that I might get away with shooting the first round on each spot with a POA on the cross marks of the target center.
Next note on the target the conditions of that first shot as far as the wind direction and strength of the wind indicated by the flag marks (look at my notes on the target top left, I think I explained how I marked the spots.
After the first shot I saw the deflection of that shot for the wind value (each first shot is marked -1 w/a line pointing to it's POI)...I simply went across the cross hairs on the opposite direction by the same amount of deflection (moved the POA against the wind direction indicated across the verticle line), left & right & over and under the horizontal. The small circles with the cross hairs in them is the 2'nd through 5'th POA for the group......I hope that makes sense.
Except for the one spot I ignored the wind, all were shot in that manner.
I was hoping that would account for the direction and speed if I were to try to shoot the remaining 4 with the same conditions as the first shot.
I thought i might get away with some easy way to read & dope without all the math involved that I've read about.
Well...it sorta didn't work.
As you can see on the spots (cross hairs of the targets) the flag directions and amplitude were sometimes in several directions...the only flag I could see when I was in the scope was the one nearest me at the bench, I can see it with my non scope eye.
THIS RABBIT HOLE JUST GOT A LOT DEEPER . . . I hope we together can figure this thing out?!
Note: One of the previous articles posted, mentions that a light .22lr projectile responds differently to the wind at sub sonic speed than our center-fires do as they are designed to help defeat the wind's influence in their weight and cruise missile shapes. There's a lot more they explained also...
